I came across this impressive home brew graphics subsystem for C64 today. The goal seems to be pushing the boundaries of what would have been possible with period-correct, through-hole 74LS parts (no FPGA or ASIC) toward advanced arcade-level graphics hardware. Quite ambitious for a one-person hobby project and, as the video below shows, very successful!
